Answer:
Cattle wear ear tags as an external form of identification.
Explanation:
There are various ways of cattle identification through several numbering systems; these are typically alphanumeric, or a simple combination of the current year and date of birth of each individual. This allows for tracking, keeping inventory and proper records on livestock at a farm. Commonly, tags are applied to the ears of cattle with applicator guns for a unique, highly visible means of identification.
These may be one of several types...
- plastic tags- usually contain a simple system of numbers, or some are left partly blank for custom tagging in special orders.
Also, a secondary tagging system may be applied to avoid misidentification, particularly in larger herds such as:
- metal tags
- electronic
- tattoos (permanent)
